# What is Salesforce Lightning?

Lightning includes the Lightning Component Framework and some exciting tools for developers. Lightning makes it easier to build responsive applications for any device.

Lightning includes these technologies:

-   Lightning components accelerate development and app performance. Develop custom components that other developers and admins can use as reusable building blocks to customize Lightning Experience and the Salesforce mobile app.
-   Lightning App Builder empowers admins to build Lightning pages visually, without code, using off-the-shelf and custom-built Lightning components. Make your Lightning components available in the Lightning App Builder so administrators can build custom user interfaces without code.
-   Experience Builder empowers admins to build communities visually, without code, using Lightning templates and components. Make your Lightning components available in Experience Builder so administrators can build community pages without code.

Using these technologies, you can seamlessly customize and easily deploy new apps to mobile devices running Salesforce. In fact, the Salesforce mobile app and Salesforce Lightning Experience are built with Lightning components.

This guide teaches you to create your own custom Aura components and apps. You also learn how to package applications and components and distribute them in the AppExchange.

To learn how to develop Lightning web components, see [Lightning Web Components Developer Guide](https://developer.salesforce.com/docs/component-library/documentation/lwc).
